ERROR: ... unable to destroy quota group: Device or resource busy
With target_qgroup_destroy yes I get errors for every subvolume on /mnt/btrfs/my-hd/:
ERROR: Failed to destroy qgroup "0/3313" for subvolume: /mnt/btrfs/my-hd/btrbk-snapshots/my-subvolume
ERROR: ... Command execution failed (exitcode=1)
ERROR: ... sh: btrfs qgroup destroy 0/3313 '/mnt/btrfs/my-hd/btrbk-snapshots/my-subvolume'
ERROR: ... unable to destroy quota group: Device or resource busy
/mnt/btrfs/my-hd/ is an internal ssd
Having this too. My backup storage accumulated a lot of stale qgroups, which I'm unable to remove.
